+# MineGeo community improvement report
+
+28 October 2026 • Review of the live homepage and Discord server
+
+Make it easy for new players to start a game, find support and discover community maps. The server already has English and Russian channels, a shared support selection, announcements and a server guide.
+
+## Changes made
+
+Updated the Discord server description to explain the game, community maps and bilingual support. Combined support selection into the existing language answers and removed the duplicate support question. Clarified the language and notification questions in English and Russian. Created the map-showcase forum with bilingual posting guidance and an optional onboarding answer. The English and Russian support channels now direct players to the bug button on the site. Sending messages and thread replies is denied to @everyone in both channels; administrator privileges and explicit role overrides can still affect access.
+
+## Recommended next steps
+
+- Make the first journey obvious: link the server guide to Play and maps, the field guide, official links and the site support button. Test it using a normal member account.
+
+- Encourage members to use the new map-showcase forum for one post per map, with a link, screenshots and spoiler warnings. Review its activity before adding more channels.
+
+- Run a small recurring community challenge: select one map, publish the deadline and rules, and invite players to share scores without revealing locations until the event ends.
+
+- Give players an optional map creator or event notification choice in onboarding, linked to a real channel or role. Keep notifications opt-in and use clear bilingual labels.
+
+- Continue applying English and Russian labels consistently across onboarding and the server guide.
+
+- Replace the image-only rules with accessible text in both languages and clarify how to report harassment or unsafe content. Keep the existing rules until the replacement is agreed.
+
+- Review the duplicate general and voice channels as membership grows; retain them for now and consolidate only after checking activity and existing content.
+
+- On the homepage, distinguish production maps from test content. The live page showed two published maps, including one labelled TEST, and two ranked players at review time.
+
+- Add a short first-game walkthrough and a prominent way to discover community maps. Explain browser and desktop options and link creators to the capture and publishing guide.
+
+- Test the support journey end to end in both languages, including mobile navigation, the bug button, submission confirmation and how users follow up. This review did not submit a real report.
+
+## Scope and limitations
+
+The site observations are from the live homepage, not a full functional or accessibility audit. Discord permissions were reviewed in the owner account; test with a regular member to confirm effective permissions. Existing channel history was preserved.

 ## Contribution server check
 
+Owners can enter up to ten connection addresses separated by commas, for example
+`play.example.com, mc.example.com:25566`. Matching any listed address is enough;
+the backend still checks every upload and retry. Older capture tools defer the
+alias check to the website. The updated tools check before uploading as well.
+
+For a map that is already published, its owner can save the draft and select
+**Publish update** to publish a validated revision without another moderator
+review. A new map still requires its initial review. This also publishes any
+player contributions the owner has already accepted into that draft.
+When uploading the owner's own contribution to an already published map, the
+contribution draft also offers **Update my map now**. It submits and accepts
+the owner's selected panoramas and publishes the update together; it refuses to
+run while the parent map has other unpublished edits.
+
 Each map has a separate **Contribution server address** setting. New maps use the address recorded by their capture tool. Existing maps with a valid captured address are initialized from their own manifest. Maps whose old exports contain no address show **Server check is off** until the owner enters one.
 
 When contributions are enabled, the map page shows that address. The owner can correct it in the dashboard, including a custom port. **Clear address and turn off check** removes the displayed address and permits submissions without matching a server. Clearing does not skip owner approval or moderator review.
